She almost deleted it. Spam, probably. But the word vermis —Latin for “worm,” and the name of the narrow, worm-like bridge connecting the two hemispheres of the cerebellum—caught her eye. That tiny structure governs balance, fine motor control, and, as her own fringe research suggested, something stranger: the brain’s subconscious rhythm.
Someone intended to remotely stimulate that man’s vermis during his address. At 14:03, his hands would tremor. His gait crossing the stage would stutter. But the PDF promised he would “correct”—meaning his healthy vermis would compensate, masking the attack as a minor neurological glitch. No one would believe him.
She opened the PDF.
The numbers were timestamps and coordinates—movement patterns. Alena’s breath caught. She’d seen similar data before, in a locked study about using pulsed magnetic fields to disrupt the vermis, causing people to lose their sense of timing. A person whose vermis is “off” can’t catch a ball, can’t walk a straight line, and—most unsettlingly—can’t perceive the natural pauses in conversation. They become socially unmoored.

It was a single page. At the top: a high-res MRI slice of a human cerebellum, the vermis highlighted in crimson. Below it, a sequence of numbers and a single line of text:
Alena closed the PDF. It had self-deleted from her computer. In its place was a new file: thank_you_vermis.pdf . She almost deleted it
The network assumed it was a strange ad-lib.
